Product Identity

The Dayton 5PXF3 is a cast iron pump strainer built for 3‑inch plumbing connections. It serves as the intake filter for compatible Dayton pool and spa pumps, keeping debris out of the impeller.

Upgrade Context

This strainer replaces a worn or missing basket on Dayton models 5PXD0 and 5PXD1. The jump is worth it when the original screen is cracked, corroded or lost, restoring full flow protection without changing the pump housing.

Interface Limits

The unit uses a 3‑inch NPT threaded intake and a 3‑inch flanged discharge, so it only fits piping with those exact sizes and thread types. Cast iron construction handles typical pool‑water chemistry but is not suited for high‑temperature or highly corrosive chemical streams.

Questions about this item

What size pipe does the 3-inch cast-iron basket strainer connect to?

It fits both a 3-inch NPT intake and a 3-inch flanged discharge on compatible Dayton pool and spa pumps.

How do you install the strainer onto the pump housing?

Thread the NPT intake into the pump inlet, bolt the flanged discharge to the pump outlet, and tighten the basket lid before priming.

When should the internal basket filter be cleaned or replaced?

Inspect the basket weekly during heavy use; clean debris immediately and replace the basket if the mesh is torn or the frame is cracked.
